… Attempts to improve the efficiency of kesterite solar … doping and alloying concepts for kesterite
absorbers with the focus on those that do not alter the parent zinc-blende derived kesterite …

… In the following, we present a review of the solutions for intrinsic and extrinsic doping of
kesterite, as well as the alloying strategies followed until now, with the aim to shed light on the …

… through doping with alkali, germanium, and other metal elements either during kesterite …
the power conversion efficiency of the kesterite absorber, doping with alkali, germanium, …

… However, the kesterite device performance is dependent on … increase the efficiency ceiling
of kesterite solar cells, making the … between Li-doping and Ag-alloying enables a reproducible …

… , but it does work in kesterite solar cells by either doping or alloying. As the radius of … alloyed
kesterite has achieved 12.3% efficiency with a fill factor of 72.7%, indicating that Ge alloying …

… Moreover, we emphasize the cation and anion doping methodologies in solution-processed
kesterites, unlike other articles discussing doping and alloying in general. Thus, this mini-…

… in CIGS, however, for CZTS with high similarity to CIGS, there are very few previous reports
10 on K doping into CZTS. Herein, we synthesize CZTS thin films with different K doping …

… in the main band gap in the four Kesterite compounds after Sb doping at Sn or Ge site, which
… Therefore, one can upshift the original VBM of Sb-doped AZGS by alloying an appropriate …

… The main conclusion is that Ge doping allows the kesterite formation mechanism to be
fundamentally changed, going from a triple reaction of binary selenides in the Ge-free case to a bi-…

Kesterite Cu2ZnSn (S, Se) 4 (CZTSSe) materials have attracted considerable interest as a
promising candidate for future thin film photovoltaic technology. This material family enjoys its …
